Tim Duncan has no interest in testing the free-agent market. While Duncan is set to become a free agent on July 1, the San Antonio Spurs veteran told Yahoo! Sports that he plans to finish his career where it started. "Though I shouldn't say that; I have to threaten them that I'll leave," Duncan joked. "No ... I'm not going anywhere. You can print that wherever you want to. I'm here and I'm a Spur for life." No surprise really,but still awesome of Duncan to get that out of the way now.
